Pseudomorphs are mineral specimens that have the external shape of one mineral but are composed of another.  The pseudomorph goethite after marcasite forms when marcasite is exposed to oxidizing conditions and starts to oxidize and break down. As the marcasite breaks down, goethite replaces it in the crystal structure, preserving the shape of the original marcasite crystal. The resulting specimen appears as a marcasite crystal, but is actually composed of goethite.

The Farafra Oasis, in the White Desert, has been known for a number of years to deliver incredible pseudomorph specimens. The pseudomorphs occur within the Cretaceous Khoman Chalk, from which the White Desert derives its name.

These specimens are remarkable for their relatively sharp marcasite crystal forms in aesthetic crystal clusters. They are in excellent condition.  This collector's specimen is unique, of great quality and ready for display.

This is a beautiful, black Biotite crystal book from Córdoba. Spain. This biotite has a classic crystal shape and attractive dark coloration. 

Biotite is rarely considered a valuable mineral specimen, but it can accompany other minerals and compliment them. In Bancroft, Ontario Biotite forms large crystals with green apatite and hornblende. Single large plates or "books" of biotite can grow to considerable size and can make impressive mineral specimens.

This is a beautiful combination of Calcite and Stilbite on Apophyllite crystal cluster.

Calcite is found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble. Stilbite is perhaps the most popular zeolite mineral for collectors. Stilbite is a handsome specimen with its pearly luster and sometimes colorful pink tints.  Apophyllite is transparent to translucent and is commonly found in colorless or white varieties, although it can also occur in shades of green, pink, yellow, or brown.

This nice crystal specimen would be a beautiful addition to any new or existing collection.

This is a natural cluster formation of large calcite crystals with hematite inclusions. This piece has some white color to translucent crystals with areas of orange/red coloring from hematite inclusions, with sharp tabular crystal formations. There are some nicks and imperfections on a few crystals but would still shine in the proper setup.  They don't take away from how interesting this piece is.  Would be a nice addition to any new or existing collection.

This is a fabulous 8.69 gram Sericho Pallasite Main Group meteorite, it measures 20x16x17.  In 2016, two brothers were searching for their camels and came across several large, dense stones west of the village of Habaswein and south of Sericho, Kenya.  Though recognized as meteorites in 2016, the masses had been known to camel-herders for decades. One village elder said that as a child, he and his brothers would play on top of the stones.  It is classified as an Iron Pallasite main group with low weathering and is 1 of only 68 approved meteorites classified as such, with a recovered weight of about 2.8 T.

This piece displays extremely well and is a nice size showing great features. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
